  Silver(I) N-heterocyclic carbene complexes: Synthesis, characterization and antibacterial activity

  摘要：

  Five new silver complexes having bidentate N-heterocyclic carbene ligands were synthesized and characterized by elemental analysis, IR, NMR and mass spectroscopic methods. Four of the ligands used are neutral, having an alcohol group on alkyl substituent of one of the two nitrogen atoms of the heterocycle [NHC-OH], the fifth, having a ligand alkoxide, is mono-anionic [NHC-O]. A study on the rate of hydrolysis of complexes synthesized, showed that they are stable to hydrolysis even after 24 h. Probably, the pincer effect of both [NHC-OH] and [NHC-O] ligands stabilizes these compounds. All the synthesized complexes do not show cytotoxicity, but they have a significant antibacterial activity. They were tested on Escherichia coli and Bacillus subtilis and data obtained demonstrate that the synthesized Ag-complexes are very promising candidates to be used as antimicrobial compounds.

  Novel octahedral zirconium complexes bearing alkoxide functionalized N‐heterocyclic carbene ligands have been synthesized and characterized. NMR analysis showed that more than one species was obtained during synthesis. The synthesized complexes were able to polymerize ethylene and propylene giving rise to a linear polyethylene with high Mw and polydispersity index often bimodal with molecular weight

  Biocatalysis, given its mild reaction conditions, is an important tool for the construction of acrylic esters, monomer assets in chemical industry, which are usually unstable against acids and heat. Several examples of ionic liquids were tested as supports for Novozym 435 in the construction of butyl acrylate Both a higher yield and a stable recyclability were found for the herein-reported glucosylimidazolium-based
